Operating & Connecting Instructions

Using 16mmsq wire

  • Connect Ground terminal to vehicle chassis.
  • Connect "Main Bat”terminal to positive terminal of the vehicle Battery. Insert a 60A fuse into this line close to the vehicle battery.
  • Connect "Aux Bat” to positive terminal of auxiliary (second) Battery
  • Red LED will blink indicating that the unit has power
  • LED will blink for 5 seconds if Ignition voltage is => 13.8 volt
  • LED will blink for 60 seconds if Ignition voltage is above 12.8 volt and below 13.8 volt
  • LED will flash slow (1 second ON - 1 second OFF) if Ignition voltage is between 6V and 12.8V.
  • The unit will not work if Ignition voltage is below 6 volt
  • Switch turns ON when Red LED turns OFF
  • Red LED turns ON solid for 10 seconds if an overload occurs. During this time the switch is open
  • Overload turn OFF delay is approximately 10 seconds for 60 Amp, 5 seconds for 100 Amp and 1 second for 150 Amp. The switch will automatically turn ON after a 10 second overload turn OFF period

Using 10mmsq wire

  • Connect Ground terminal to vehicle chassis.
  • Remove the link between the "Main Bat” and "Ign” terminal
  • Connect "Main Bat” terminal to positive terminal of the vehicle Battery. Insert a 60A fuse into this line close to the vehicle battery.
  • Run a 1.5mmsq wire from the "Ign" terminal to the 60A fuseat the vehicle battery 
  • Connect "Aux Bat” to positive terminal of auxiliary (second) Battery
  • Red LED will blink indicating that the unit has power
  • LED will blink for 5 seconds if Ignition voltage is => 13.8 volt
  • LED will blink for 60 seconds if Ignition voltage is above 12.8 volt and below 13.8 volt
  • LED will flash slow (1 second ON - 1 second OFF) if Ignition voltage is between 6V and 12.8V.
  • The unit will not work if Ignition voltage is below 6 volt
  • Switch turns ON when Red LED turns OFF
  • Red LED turns ON solid for 10 seconds if an overload occurs. During this time the switch is open
  • Overload turn OFF delay is approximately 10 seconds for 60 Amp, 5 seconds for 100 Amp and 1 second for 150 Amp. The switch will automatically turn ON after a 10 second overload turn OFF period
Battery Monitor Terminals
  • The unit is provided with two battery monitor terminals that can be connected to a battery monitor
  • Terminal M1 is connected to the main battery and terminal M2 is connected to the auxiliary battery
  • KEEP IN MIND THAT M1 & M2 ARE CONNECTED TOGETHER WHEN THE SWITCH IS CLOSED

Warning
Mount in cool place
Do not short Battery leads
